About an hour ago I had something odd happen. Earlier today I purchased a new speaker mic for my handi-talkie. So, as I'm out and about this afternoon I've had the HT clipped to my belt and the mic attached to the lapel of my jacket. Well, I walk into the gazebo where our mailbox is located - we live in an apartment community - and my radio went completely silent. It didn't make any sense because it is open all the way around including the roof which has a faux bell tower. As soon as I walked back into the parking lot, it started working again. All I can figure is, since the gazebo is the lowest point in the community, the signal was just shooting right over the top of me. Anybody have other theories/explanations?
